scope:

This standard applies to the track geometry on track through and on the approach to each WILD location.

Purpose

Wheel Impact Load Detection systems, such as Gotcha, identify vehicles with significant wheel defects and produce real-time information. This allows the risk of track damage or derailment to be reduced through identifying trains with wheel defects which are then run at slower speed or, in extreme cases, stopped.

Failure to maintain the track in accordance with this document will result in equipment being switched off, and track damaging wheelsets going undetected, which could result in broken rails and derailment.
